EFFICACY OF CLOMIPHENE CITRATE IN INDUCING OESTRUS IN BITCHES
Shibu Simon and K.V. Athman

Dogs are monoestrous, usually non-seasonal, polytocous, spontaneous ovulators (Concannon, 1991). During each oestrous cycle the bitch has a prolonged follicular and luteal phase, compared to those of the cycling species of farm animals. Such an ovarian activity, unique only to the bitch among domestic animals creates problems in formulating efficient breeding programmes. More over the costs of maintaining an anoestrous bitch makes commercial dog breeding expensive. Shortening the naturally long anoestrous phases of the oestrous cycle in the bitch could increase fecundity. The present work was therefore undertaken with the objective of assessing the efficacy of
